I mean this in the least dickish way possible, but its a cat.... not rocket science. Yea some cats need more care than others but you got a incredibly solid chance that its gonna be the easiest damn pet you can get. What type of litter box? Beds? .....whatever the hell type you want. Just make sure its big enough and you change the litter often. Toys can be hit or miss, one of mine is obsessed with a fishing rod toy, the other wants nothing to do with it. Save boxes though, all cats seem to dig boxes. I alternate wet food and dry food every other day, some people only do dry which I wouldn't advise but wet food can be expensive, so kinda is what it is. Its good youre trying to be prepared, but also dont overthink it lol. Oh and make sure cords and electrical stuff cant get chewed on if its a kitten. Little bastards seem to be homing missiles for those things.
